My mom was married two different times. She was married to my father for 16 years before he died from cancer. While their marriage was not perfect, they worked through their problems and truly loved one another. They made their life adventurous and fun and included us three girls in most everything they did.
My mother married my stepfather ten years after my father died. She had gone through many trials and tribulations through those ten years because she did not know how to live without the love of her life. My stepfather had gone through similar issues after a horrible divorce. Both had become alcoholics and for many years tried to drink their problems away.
Once they met, it was miracle that happened. Both stopped drinking and went back to the good, hardworking people they had once been. They were married for more than twenty years when my mom passed away.
Both of my mother's marriages were filled with love and happiness and both were different and wonderful in their own ways.
So, yes, my parents' marriages were wonderfully happy!
